I loved the cast and the concept was refreshing in some ways, but I agree its cancellation was a blessing in disguise. It would have been nice to see certain storylines get to play to their conclusion (I'm fond of the movie but its attempt to jam all that resolution into two hours largely failed), but after that it could've gotten stale pretty quickly.To me, the show was better off exploring life after a revolution gone wrong, focused on a group of people finding home in the midst of an imperfect future. It being cancelled kept the show sticking to what made it work.
Also, for all that I'm fond of it, there were huge ways in which the execution was flawed. In particular, the Western metaphor was too literal by half (and the Civil War theme so on-the-nose that it bore an uncomfortable family resemblance to neo-Confederate Romanticism in Spaaace), to the point where it literally had them carrying cattle from planet to planet at one point. I was sad that it got cancelled but not surprised.
